Cytochrome C

This biomarker is also known as:
  • THC4,
  • Cytochrome C, Somatic,
  • HCS,
  • cyto C,
  • CYCS,
  • CYC,
  • Cytochrome C,


CYCS, or cytochrome C, is an electron carrier protein that is an important part of the electron transport chain in mitochondria. The cytochrome C protein is a small heme protein that associates with the inner membrane of the mitochondrion where it accepts electrons from cytochrome b and transfers them to the cytochrome oxidase complex. Cytochrome C also plays a role in apoptosis.

Performance Comment

Cytochrome C belongs to a 9-member panel that provides a quantitative measure of the probability of having lung cancer that goes beyond the histological evaluation of preinvasive lesions. The identified members of the panel are TMSB4X (Thymosin beta-4), Ubiquitin, des-ubiquitin, ACBP, CSTA, Cytochrome C, and MIF.
